Now as far as TLR wheelsets go, all of mine have been UST. TLR rims come in different flavors. To my knowledge, there is no standard for what constitutes a TLR rim. With UST you have a sealed rim-bed and a bead of a particular shape. UST is a certification. Somebody could make a UST rim and not get it certified and it wouldn't be UST. So for example Fulcrum and Campy's 2-Way Fit rims are for all intents and purposes UST rims and can be treated as such, but are not UST certified.

Hmmm...interesting.  I guess I should just try it -- put a UST tire on the rim, pump it up and see if it catches and holds air.  If not, just add some Hutchinson sealant.  FWIW, I have Bontrager Rhythm Comp TLR 29er wheels.  I haven't found any comments on the web from people who've run this wheel as a true UST.

Have you ever tried Geax Tubeless Therapy sealant? It looks like a similar product to the Hutchinson stuff.  Claimed to last 2 years.

Cheers!
